With the influence of VoIP long distance was deregulated in Israel. According to the Israel Ministry of Communication a VoIP number may be ported to a landline carrier and vice versa providing the option to have, say, a northern number in the south of the country. Numbers may not be ported, say, from the north to the south of the country on the same kind of line (e.g., VoIP to VoIP or landline to landline). Mobile number portability between cellular providers was introduced in late 2007.

The format for calls to landlines within the same area code is XXX-XXXX (7 digits subscriber number). For calls to a landline outside the local area, the area code is prefixed and the format becomes (0A) XXX-XXXX for calls to landlines, where "0A" is the area code.

The format for calls to cellular mobile phones is 05N-XXX-XXXX, where "05N" is the mobile operator indicator. The format for calls to VoIP lines is 07N-XXX-XXXX, where "07N" is the VoIP operator indicator.

When calling from outside of Israel, the leading "0" in area codes is not dialed, and the format is +972-A-XXX-XXXX for calls to landlines, +972-5N-XXX-XXXX for calls to mobile lines, +972-7N-XXX-XXXX for calls to VoIP lines.

Kosher phones and networks are essentially phones with Haredirabbinical approval that can be used for communication without entertainment functionality or connectivity. This is a line that has a pre-defined prefix and it is blocked to content that Haredi activists feel is not appropriate for their community. Such blocking includes cellular internet access, chat rooms, SMS, etc. It should not be imputed that other phones are not kosher according to Jewish law, as evidenced by the fact that a very large number - if not the majority - of observant Orthodox Jews worldwide do not restrict themselves to "kosher" phones; rather the description "kosher" phones is a loose one, implying an added level of stringency accepted by some communities.

Some mobile plans include a large allocation of minutes to kosher numbers, which are:
